CONDENSING MECHANISM FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 243,241, dated June 21,1881.

Application filed March 31, 1881.

1" all whom it may concern Be it known that I, MERRILL A. FURBUSH,acitizen of the United States, residingin Philadelphia, Pennsylvania,have invented an Improvement in Oonden singMechanism forCarding-Machines, of which the following is a specification.

My invention consists of the combination, in

a carding-machine, of a series'of ordinary ro- IO tating andreciprocating rub-rolls with reciprocating andtraversing aprons, theobject of my invention being to obtain the superior con- (lensingefl'ect of the aprons and the drawing and stretching effect of therolls, which effect cannot be produced by the aprons alone.

In the accompanying drawings, Figure 1 is a plan view, showing the rubrolls of a cardingmachine combined with the aprons; and Fig. 2, avertical section on the line 1 2.

A A, Fig. 1, represent portions of the fixed frame of a carding-machine;and B a reciprocating bar adapted to guides on or forming part of theframe, and carrying the bearings a tor the journals 1) of the series ofrub-rolls D, 2 5 1), D E, and E, another reciprocating bar below thefirst carrying the bearin gs for the journals of another setofrub-rolls, G, G, G F, and F, Fig. 2. The two bars are reciprocate'd incontrary directions by eccentrics H and I, as 0 described in the LettersPatent No. 166,601,

granted to me August 10, 1875.

The shafts b of the rub-rolls pass through and are arranged to slide inand turn with a series of cog-wheels, the hubs of which are 3 5 adaptedto a series of bearings, d, on the fixed frame A, the upper and lowerset of rolls being geared together by the said wheels, so as to revolvein the direction of the arrows, Fig. 2.

An endless apron, K, of leather or other 40 suitable material, passesround the rollers E (No model.)

E, and another endless apron, K, round the rollers F F.

The slivers stripped from the stripper-cylinder of the carding-machinepass, in the direction of the arrow, first between the upper and lowerset of rub-rolls, and thence between the aprons which movein thedirection of the arrows, while they are reciprocated in contrarydirections simultaneously with the rub-rolls.

The rolling and condensing of the slivers can be more thoroughlyaccomplished by the combined effect of the two aprons than by therub-rolls; butthe latter possess this advantage, that there can be aslight drawing or stretching of the slivers as they pass between therolls, it being the practice in many carding-engines to adopt suchgearing that there will be a slight progressive increase in the speed ofthe rollers from the first to the last, so as to produce the desireddrawing effect.

By combining a series of revolving and reciprocating rolls with thereciprocating and traversing aprons, I gain the advantages of bothsystems, while the combination presents the opportunity of drawing orstretching the slivers as they leave the last rollers and before theyare seized by the aprons.

I claim as my invention.

The combination, in a carding-machine, of rotating and reciprocatingrub-rolls with traversin g and reciprocating aprons, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

MERRILL A. FURBUSH.
